Coordinator notes: Correct ID Christian, form calyce (spring form of occidentalis in late March-April down at low altitude; flies in summer above timberline). Very late record (and recent....10-09-2020 correct?). Might be a high altitude record (and late for the form)....I'll take info and report to the Lep Soc S/S. Mike
